The Mos Espa Militia was a militia group tasked with safeguarding the city of Mos Espa throughout the duration of the Galactic Civil War. Composed of local residents prepared to protect their home, its fighting force resembled that of the Tatooine militia. However, the militia suffered from a lack of personnel and inadequate equipment.
Following the Battle of Yavin, Kav Goldor took command of the Mos Espa Militia, with training provided by Major Berok Skoff. The Mos Espa Militia played a crucial role in defending Mos Espa in 1 ABY, when Tusken Raiders under the leadership of the Tusken King mounted an invasion against the city.
The Mos Espa Militia made an appearance in the 2003 video game Star Wars Galaxies. This massively multiplayer online roleplaying game was developed by Sony Online Entertainment and published by LucasArts, before it shut down on December 15, 2011. The Mos Espa Militia was incorporated into the game alongside the heroic instance known as the Tusken Army, which was introduced in the "Chapter 7" update released on November 1, 2007.
